Application of Integral

Integrals are areas between the graph of a function and the horizontal axis. ... Some applications of integrals are: Displacement, which is the integral of velocity with respect to time. Change in velocity, which is the integral of acceleration with respect to time. Averages of functions between set boundaries.

What is the use of integration in real life?
Calculus is used to improve the architecture not only of buildings but also of important infrastructures such as bridges. In Electrical Engineering, Calculus (Integration) is used to determine the exact length of power cable needed to connect two substations, which are miles away from each other.
What is the use of integral calculus?
Among the disciplines that utilize calculus include physics, engineering, economics, statistics, and medicine. It is used to create mathematical models in order to arrive into an optimal solution. For example, in physics, calculus is used in a lot of its concepts.
